Does anyone know the best emissivity values for standard building products like drywall, wood, rofing materials etc.?

Well, I suppose it depends on how accurate you have to be in your IR measurements. I generally use .90 to .95, depending on what is being looked at, and what the finish of the material is. You also have to take other things into consideration as well, but I'm presuming you are aware of that.
